Hi all,
I have developed a labview project to acquire data continuously from my FPGA device (NI USB 7856R) and later plot it in excel. After a series of debugging attempts, I am still left with one. I am applying a test signal: sine wave (through signal generator device) of 100Khz 1Vpp at input and expect the same at output. However I do not get a perfect sine wave but it experiences a certain DC offset. (Please find the attached waveform) I tested my signal generator itself and it works fine.
Also I face another issue. When I apply absolutely no input, the waveform plots a straight line of -10.5 V. I don't understand the reason behind it.
Please find the attached project and respective VIs. Any help is appreciated.
Thank You !
P.S: Please refer to attached VIs only. I apologize for the excess VIs and messy organisation.
Regards
Pratik
